Title: Improvements in or relating to a device for setting the diaphragm of an objective
IPC: G03B9/07
Filed: 1961-03-29
Abstract: 973,436. Adjusting diaphragms. PAILLARD S. A. March 29, 1961 [March 29, 1960], No. 11497/61. Heading G2A. A device for adjusting and setting the diaphragm of an objective comprises, as shown in Fig. 1, a rotatable diaphragm ring 1 controlling the opening of the diaphragm and carrying a control knob 2. A stop ring 3 carrying a stop pin 4 engaging a slot 5 in the ring 1 for limiting movement of that ring is releasably locked in a fixed position by means of a pawl 6 pivoted on the ring 3 and having an end 6a urged by a spring 9 into clamping engagement with a part 10 of the objective mount. The pawl 6 is provided with a control knob 8 and by urging this in the direction of the arrow F, both rings 1 and 3 may be moved into a desired aperture position as determined in known manner with the help of an exposure meter, the photo-cell of which is placed behind the objective. Ring 1 may then be rotated into its maximum aperture position (for example to enable a single-lever reflex camera to be focused) before returning it into the pre-selected aperture position as now determined by the engagement between the pin 4 and the level end of slot 5. In a modification (Fig. 2), ring 3 is formed as a split ring which resiliently engages the tube 10 and thereby locks ring 3 against rotation-said lock being released by urging of the two knobs 2 and 8 towards one another. The stop pin 11 is in this case carried by the ring 1.

Title: Production of smooth surfaces on vitreous bodies
IPC: C03B23/09
Filed: 1964-03-19
Abstract: In a method of producing a smooth outer surface shaped to a high degree of precision on a glass article, a preformed article of approximately the final dimensions and at a temperature at the lower end of the working range of the glass is placed in a moulding tool machined to within very fine tolerances and at a temperature at the upper end of the transformation range of the glass, the outer surface of the preform being brought into contact with the moulding surface, and the article being removed from the moulding tool after the outer zone of the tool has cooled to a temperature at least as low as the lower end of the transformation range of the glass.  In the example, a tube 1 is clamped very accurately within a lathe and one end closed off by any known means.  Rollers 2 and 3 which also rotate are brought into contact with the closed end of the rotating tube which <PICT:1063467/C1/1> <PICT:1063467/C1/2> is heated to about 800 DEG C. in a flame 4, 41. Simultaneously air under slight pressure is blown down the tube to cause the closed end to assume a hemispherical shape.  This shapes a preform the diameter of which is within 0.1 mm. of that finally required. The preformed section is then introduced into a mould 5 which is pre-heated to about 590 DEG C. and is also rotatable. Air is blown down the tube to cause the preform to expand into contact with the mould. When the mould 5 has cooled through about 70 DEG C. the article is removed.

Convention date, May 19, 1931. [Class 55 (i).] A process of distilling bituminous schists consists in breaking up the material to grains of 10 to 15 mm. diameter, drying the grains, and passing them through a rotating drum of about 11 metres in length externally heated to about 750‹ C., while steam and an inert gas flow through the drum in an opposite direction, the heating process lasting about a quarter of an hour. The schist from a hopper 7 is passed through a dryer 9 and delivered from a shoot 12 into a rotary steel drum 1 having helical ribs 14, and a longitudinal rib which agitates the material. The hot residue falls through a bell 15 into a water-trough 16, the steam from which passes through the drum, accompanied if necessary by steam from an inlet 17 superheated to 250‹ C. and an inert gas. The distillates are withdrawn through an outlet 13 under a vacuum of about 100 mm. water.
